थर्मोकपल को समझना: एक व्यापक अवलोकन

तापमान माप के क्षेत्र में, थर्मोकपल वे महत्वपूर्ण उपकरण होते हैं जो बहुमुखी, टिकाऊ और व्यापक रूप से उपयोग किए जाने वाले सेंसर के रूप में सामने आते हैं। वे सीबेक प्रभाव के सिद्धांत पर कार्य करते हैं, जिसमें तापमान भिन्नता के जवाब में 2 अलगअलग धातुओं के जंक्शन द्वारा एक वोल्टेज उत्पन्न होता है। विभिन्न प्रकार के थर्मोकपल हैं, जिनमें से कुछ विशिष्ट तापमान सीमाओं के साथसाथ वातावरण के लिए भी उपयुक्त हैं।

थर्मोकपल के प्रकार

  • बीप्रकार के थर्मोकपल: बीप्रकार के थर्मोकपल का उपयोग अक्सर उच्च तापमान वाले वातावरण में किया जाता है। प्लैटिनमरोडियम मिश्र धातु (PtRh30-PtRh6) के साथ डिज़ाइन किए गए, ये बीप्रकार के थर्मोकपल 1700 डिग्री सेल्सियस तक मापने वाले अत्यधिक उच्च तापमान परिदृश्यों को पूरा करते हैं, जो उन्हें रासायनिक और अर्धचालक उद्योगों में अनुप्रयोगों के लिए उपयुक्त बनाते हैं। वे एयरोस्पेस, सेमीकंडक्टर विनिर्माण और कुछ प्रयोगशाला अनुप्रयोगों जैसे उद्योगों में भी उत्कृष्टता प्राप्त करते हैं।
  • आरप्रकार के थर्मोकपल: आरप्रकार के थर्मोकपल में प्लैटिनमरोडियम मिश्र धातु (PtRh13-Pt) होता है और यह 1600°C तक तापमान सहन कर सकता है। अपनी उच्च सटीकता और अच्छी स्थिरता के लिए जाने जाते हैं वे आमतौर पर प्रयोगशालाओं, औद्योगिक सेटिंग्स और रिफाइनिंग प्रक्रियाओं आदि में पाए जाते हैं। सटीकता के बावजूद, ये आरप्रकार के थर्मोकपल हजारों डिग्री से ऊपर के तापमान पर अत्यधिक प्रतिक्रियाशील हो जाते हैं और खराब हो सकते हैं। आसानी से दूषित हो सकते हैं। इसलिए, उनकी सटीकता और स्थिरता का कम तापमान वाली गतिविधियों जैसे सल्फर रिकवरी इकाइयों आदि में बेहतर उपयोग किया जाता है।
  • एसप्रकार के थर्मोकपल: आरप्रकार के थर्मोकपल के समान, ये एसप्रकार के थर्मोकपल प्लैटिनमरोडियम मिश्र धातु (PtRh10-Pt) का उपयोग करते हैं और उच्च तापमान का सामना करते हैं। इन्हें मुख्य रूप से 1600 डिग्री सेल्सियस तक मापने वाले उच्च तापमान अनुप्रयोगों में नियोजित किया जाता है। उनके अनुप्रयोगों में धातुकर्म, धातु शोधन सिरेमिक, चिकित्सा उद्योग और उच्च तापमान वाली रासायनिक प्रक्रियाएं शामिल हैं।
  • प्रकार के थर्मोकपल: क्रोमेल (90% निकल और 10% क्रोमियम) और कॉन्स्टेंटन (45% निकल और 55% तांबा) की विशेषता वाले, प्रकार के थर्मोकपल एक व्यापक तापमान रेंज (-270 डिग्री सेल्सियस से 1000 डिग्री सेल्सियस) को कवर करते हैं। ये बहुत लागत प्रभावी भी हैं. वे एचवीएसी सिस्टम, खाद्य प्रसंस्करण और प्रयोगशाला उपकरणों में उपयोग के लिए आदर्श हैं। इन प्रकार के थर्मोकपल में उच्च आउटपुट, तेज़ प्रतिक्रिया समय और गैरचुंबकत्व होता है। ये विशेषताएँ उन्हें क्रायोजेनिक्स, विमान और प्रवाह कक्षों आदि में उपयोग के लिए उपयुक्त बनाता है।
  • जेप्रकार के थर्मोकपल: लौह और कॉन्स्टेंटन मिश्र धातुओं से युक्त, जेप्रकार के थर्मोकपल एक मध्यम तापमान रेंज (-210 डिग्री सेल्सियस से 1200 डिग्री सेल्सियस) प्रदान करते हैं। उनकी लागतप्रभावशीलता और बहुमुखी प्रतिभा उन्हें विभिन्न औद्योगिक और घरेलू अनुप्रयोगों के लिए उपयुक्त बनाती है। इसलिए, उनकी सामर्थ्य और मध्यम तापमान सीमा के कारण इनका उपयोग आमतौर पर औद्योगिक अनुप्रयोगों और घरेलू उपकरणों में किया जाता है। इन जेप्रकारों का उपयोग आमतौर पर तारों पर बनने वाले संघनन के कारण परिवेश के तापमान के नीचे नहीं किया जाता है क्योंकि इससे लोहे में जंग लग जाती है। इसलिए, इनमें केप्रकार की तुलना में उच्च तापमान पर छोटी तापमान सीमा और कम जीवनकाल होता है।
  • एनप्रकार के थर्मोकपल: एनप्रकार के थर्मोकपल में निकलक्रोमियमसिलिकॉन और निकलसिलिकॉनमैग्नीशियम मिश्र धातु होते हैं। -270°C से 1300°C की तापमान सीमा के साथ, वे उच्च तापमान ऑक्सीकरण के लिए उत्कृष्ट प्रतिरोध प्रदान करते हैं। उच्च तापमान ऑक्सीकरण के प्रति उनके प्रतिरोध के कारण, वे अक्सर एयरोस्पेस और परमाणु उद्योगों में अपना अनुप्रयोग पाते हैं। केप्रकार की प्रतिद्वंद्वी सटीकता और कीमत बिंदु को देखते हुए, इन एनप्रकार को आरप्रकार और एसप्रकार के लिए बेहतर विकल्प माना जाता है।  
  • केप्रकार के थर्मोकपल: सबसे व्यापक रूप से उपयोग किए जाने वाले थर्मोकपल में से एक, केप्रकार के थर्मोकपल क्रोमेल और एलुमेल मिश्र धातुओं का उपयोग करते हैं। वे व्यापक तापमान रेंज (-270°C से 1372°C) को कवर करते हैं। वे अपनी विस्तृत तापमान सीमा और विश्वसनीयता के कारण उत्पादन, ऑटोमोटिव और एचवीएसी सिस्टम में उपयोग के लिए व्यापक रूप से उपयुक्त हैं। हालांकि ये सटीक हो सकते हैं, फिर भी 750 के आसपास और उससे ऊपर के तापमान के लिए उपयोग किए जाने पर इन्हें पुन: अंशांकन की आवश्यकता होती है। यदि संक्षारक प्रतिरोध प्राथमिक चिंता का विषय हो तो उत्कृष्ट धातु प्रकार वैकल्पिक होते हैं। ये विश्वसनीय, लागतकुशल और विस्तृत तापमान सीमा के साथ सटीक हैं।
  • टीप्रकार के थर्मोकपल: तांबे और कॉन्स्टेंटन मिश्र धातुओं से बने, टीप्रकार के थर्मोकपल -270 डिग्री सेल्सियस से 400 डिग्री सेल्सियस तक तापमान सीमा को कवर करते हैं। वे काफी स्थिर हैं और -59 से 370 (-75 से +700) के बीच सबसे अच्छा काम करते हैं, जो उन्हें क्रायोजेनिक्स और अल्ट्रालो फ्रीजर जैसी कम तापमान वाली प्रयोगशाला प्रक्रियाओं के लिए सबसे अच्छा विकल्प बनाता है। ये टीप्रकार -200 और 200 के बीच के माप के अनुरूप हैं। ये विघटनप्रतिरोधी भी हैं! इसलिए, संक्षारण प्रतिरोधी होने के कारण, इन प्रकारों का उपयोग आमतौर पर खाद्य उद्योग, फार्मास्यूटिकल्स और एचवीएसी अनुप्रयोगों में किया जाता है।

नोबल मेटल थर्मोकपल क्यों और कैसे महत्वपूर्ण हैं?

थर्मोकपल ऐसे उपकरण हैं जिनका उपयोग आमतौर पर औद्योगिक सेटिंग्स में उच्चतम क्रम के तापमान को मापने के लिए किया जाता है जहां वस्तुओं को अत्यधिक उच्च तापमान पर गर्म करने की आवश्यकता होती है। ये थर्मोकपल या तापमान सेंसर दो अलगअलग धातुओं से बने होते हैं जो तापमान को मापने के लिए एक विशेष जंक्शन पर मिलते हैं। दोनों धातुओं का ताप से अलगअलग संबंध होता है, इसलिए जब इस जंक्शन को गर्म किया जाता है, तो एक वोल्टेज उत्पन्न होता है। तापमान निर्धारित करने के लिए इस वोल्टेज को मापा जा सकता है।

नोबल मेटल थर्मोकपल अन्य धातुओं की तुलना में सबसे कम प्रतिक्रियाशील होते हैं!

यह उत्कृष्ट धातुओं की अद्वितीय प्रतिक्रियाशीलता विशेषता है जो उन्हें विशेष रूप से अत्यधिक तापमान स्थितियों में उपयोग करने के लिए उपयुक्त बनाती है। ये धातुएँ अन्य धातुओं की तरह प्रतिक्रियाशील नहीं होती हैं, इसलिए इनके संक्षारण की संभावना कम होती है। उनका गलनांक भी अधिक होता है, इसलिए वे उच्च तापमान का सामना कर सकते हैं। नोबल मेटल थर्मोकपल अन्य थर्मोकपल की तुलना में अधिक सटीक होते हैं, लेकिन वे अधिक महंगे भी होते हैं। रोडियम और प्लैटिनम दो ऐसी उत्कृष्ट धातुएँ हैं जिनका व्यापक रूप से अत्यधिक संवेदनशील और सटीक तापमान संवेदन उपकरण बनाने में उपयोग किया जाता है, भले ही वे महंगे हों। इनका उपयोग आमतौर पर उन उद्योगों में किया जाता है जहां सटीक तापमान माप महत्वपूर्ण होते हैं जैसे उच्च तापमान भट्टियां और बॉयलर।

नोबल मेटल थर्मोकपल के तीन मुख्य प्रकार हैं!

नोबल मेटल थर्मोकपल वे थर्मोकपल हैं जो अपनी सटीकता और परिशुद्धता के लिए जाने जाते हैं। उत्कृष्ट धातु थर्मोकपल के तीन मुख्य प्रकार हैं: आर प्रकार, एस प्रकार, और बी प्रकार। प्रत्येक प्रकार की तापमान परिवर्तन के प्रति अपनी संवेदनशीलता होती है।

  • आर प्रकार के थर्मोकपल रोडियम और प्लैटिनम से बने होते हैं जो तापमान परिवर्तन के प्रति सबसे अधिक संवेदनशील होते हैं और व्यापक तापमान रेंज, यानी -50 से 1400 डिग्री सेल्सियस तक काम करने में सक्षम होते हैं। इनका उपयोग अक्सर उन अनुप्रयोगों में किया जाता है जहां सटीक माप की आवश्यकता होती है, जैसे प्रयोगशालाओं में।
  • एस प्रकार के थर्मोकपल आर प्रकार के थर्मोकपल की तुलना में तापमान परिवर्तन के प्रति कम संवेदनशील होते हैं और उनकी सीमा -50 डिग्री सेल्सियस से 1200 डिग्री सेल्सियस होती है। वे पैलेडियम और प्लैटिनम से बने होते हैं और अक्सर औद्योगिक अनुप्रयोगों में उपयोग किए जाते हैं जहां सटीकता उतनी महत्वपूर्ण नहीं होती है। वे संक्षारण के प्रति अधिक प्रतिरोधी हैं, हालांकि आर प्रकार की तुलना में थोड़ा कम सटीक हैं।
  • बी प्रकार के थर्मोकपल सिलिकॉन और बोरॉन से बने सभी उत्कृष्ट धातु थर्मोकपल के तापमान परिवर्तन के प्रति सबसे कम संवेदनशील होते हैं। इनकी ऑपरेटिंग रेंज -50 डिग्री सेल्सियस से 1000 डिग्री सेल्सियस के बीच होती है।

नोबल मेटल थर्मोकपल तापमान मापने के लिए बहुत सटीक उपकरण हैं। आपके द्वारा चुने गए थर्मोकपल का प्रकार उस एप्लिकेशन के लिए आवश्यक संवेदनशीलता पर आधारित होना चाहिए जिसमें आप इसका उपयोग कर रहे हैं, जिसके लिए आप डोमेन विशेषज्ञों से पूछ सकते हैं जो आवश्यक तापमान संवेदनशीलता और अन्य शर्तों को पूरा करने के लिए आपके लिए अनुकूलित कर सकते हैं। आप उत्पादों की सर्वोत्तम श्रृंखला के लिए हीटकॉन से संपर्क करें।

 

 

 

थर्मोकपल अंशांकन की प्रक्रिया का विवरण

थर्मोकपल अंशांकन के बारे में

थर्मोकपल अंशांकन थर्मोकपल के तापमान माप की सटीकता को सत्यापित और समायोजित करने की प्रक्रिया है। इसमें थर्मोकपल के आउटपुट की तुलना ज्ञात तापमान पर एक संदर्भ मानक से करना और किसी भी विचलन या त्रुटि का निर्धारण करना शामिल है। अंशांकन यह सुनिश्चित करता है कि थर्मोकपल सटीक और विश्वसनीय तापमान रीडिंग प्रदान करता है, जिससे सटीक तापमान नियंत्रण और प्रक्रिया अनुकूलन की अनुमति मिलती है।

 

थर्मोकपल अंशांकन की तकनीकें

थर्मोकपल अंशांकन की 3 सामान्य विधियाँ हैं:

  • फिक्स्डपॉइंट थर्मोडायनामिक कैलिब्रेशन: इस विधि में, थर्मोकपल को ज्ञात तापमान के निश्चित बिंदुओं के विरुद्ध कैलिब्रेट किया जाता है, जैसे धातु या नमक जैसे शुद्ध पदार्थों के पिघलने बिंदु। निश्चित बिंदुओं के उदाहरणों में चांदी का हिमांक बिंदु (961.78°C) और पानी का त्रिगुण बिंदु (0.01°C) शामिल हैं। इन निश्चित बिंदुओं पर ज्ञात तापमान के साथ थर्मोकपल के आउटपुट की तुलना करके, अंशांकन समायोजन किया जा सकता है।
  • फर्नेस विधि: इसे स्टिरर्ड बाथ विधि भी कहा जाता है, इसमें थर्मोकपल को तापमान नियंत्रित स्नान या भट्टी में डुबोना शामिल है। स्नानघर या भट्ठी को पूरे क्षेत्र में एक स्थिर और समान तापमान प्राप्त करने के लिए डिज़ाइन किया गया है। तापमान को कैलिब्रेटेड रेफरेंस थर्मामीटर का उपयोग करके मापा जाता है। विभिन्न तापमानों पर थर्मोकपल और संदर्भ थर्मामीटर की रीडिंग की तुलना करके, अंशांकन सुधार निर्धारित किया जा सकता है।
  • ड्राई ब्लॉक कैलिब्रेटर: यह एक पोर्टेबल डिवाइस होता है जिसमें एक धातु ब्लॉक होता है जिसमें सटीक रूप से ड्रिल किए गए छेद होते हैं जहां थर्मोकपल डाला जा सकता है। अंतर्निहित हीटर या कूलर का उपयोग करके ब्लॉक को विशिष्ट लक्ष्य तापमान तक गर्म या ठंडा किया जाता है। ब्लॉक तापमान को कैलिब्रेटेड रेफरेंस थर्मामीटर का उपयोग करके मापा जाता है। अंशांकन के तहत थर्मोकपल को ब्लॉक में डाला जाता है, और इसके आउटपुट की तुलना संदर्भ थर्मामीटर रीडिंग से की जाती है, जिससे अंशांकन समायोजन की अनुमति मिलती है।

 

थर्मोकपल अंशांकन की आवश्यकता

विभिन्न उद्योगों में तापमान मापने के लिए थर्मोकपल का व्यापक रूप से उपयोग किया जाता है। हालाँकि, समय के साथ, उम्र बढ़ने, अत्यधिक तापमान के संपर्क में आने, यांत्रिक तनाव और पर्यावरणीय परिस्थितियों जैसे कारकों के कारण उनकी सटीकता कम हो सकती है। अंशांकन इन विचलनों को पहचानने और ठीक करने में मदद करता है, जिससे यह सुनिश्चित होता है कि थर्मोकपल सटीक तापमान रीडिंग प्रदान करता रहे।

 

थर्मोकपल अंशांकन के लिए आवश्यक आवृत्ति

कितनी बार थर्मोकपल अंशांकन की आवश्यकता होती है यह काफी हद तक विभिन्न कारकों पर निर्भर करता है, जैसे कि एप्लिकेशन का प्रकार जिसके लिए आपको थर्मोकपल की आवश्यकता है, उद्योग मानक, साथ ही नियामक आवश्यकताएं। सामान्य तौर पर, महत्वपूर्ण प्रक्रियाओं या सुरक्षामहत्वपूर्ण अनुप्रयोगों में उपयोग किए जाने वाले थर्मोकपल को अधिक बार कैलिब्रेट किया जाना चाहिए, आमतौर पर साल में एक बार से लेकर हर कुछ महीनों में एक बार। कम महत्वपूर्ण अनुप्रयोगों को हर 1-2 साल में अंशांकन की आवश्यकता हो सकती है।

 

अंतिम अंशांकन तिथि का निर्धारण

यह जानने के लिए कि अंतिम थर्मोकपल अंशांकन कब किया गया था, आपको उचित दस्तावेज़ और रिकॉर्ड बनाए रखना चाहिए। मान्यता प्राप्त अंशांकन प्रयोगशालाओं द्वारा प्रदान किए गए अंशांकन प्रमाणपत्रों में आम तौर पर अंशांकन तिथि, नियत तारीख और अन्य प्रासंगिक जानकारी शामिल होती है। इसलिए इन प्रमाणपत्रों पर नज़र रखना या अंशांकन लॉग बनाए रखना महत्वपूर्ण है ताकि यह सुनिश्चित किया जा सके कि थर्मोकपल अपने अंशांकन शेड्यूल के भीतर बना रहे।

 

गुणवत्ता प्रमाणपत्र

थर्मोकपल को मान्यता प्राप्त अंशांकन प्रयोगशालाओं द्वारा प्रमाणित या कैलिब्रेट किया जा सकता है जो आईएसओ/आईईसी 17025 जैसे अंतरराष्ट्रीय मानकों का पालन करते हैं। ये प्रयोगशालाएं ट्रेस करने योग्य संदर्भ मानकों का उपयोग करती हैं और अंशांकन करने के लिए योग्य कर्मियों को नियुक्त करती हैं। इन प्रयोगशालाओं द्वारा प्रदान किए गए अंशांकन प्रमाणपत्र थर्मोकपल की सटीकता और गुणवत्ता मानकों के अनुपालन के प्रमाण के रूप में काम करते हैं।

 

सर्वोत्तम थर्मोकपल की खरीद के लिए

थर्मोकपल अंशांकन के लिए अलगअलग दृष्टिकोण पेश करने वाली विभिन्न विधियाँ हैं, और विधि का चुनाव आवश्यक सटीकता, उपलब्ध उपकरण और विशिष्ट अनुप्रयोग जैसे कारकों पर निर्भर करता है। सर्वोत्तम थर्मोकपल की खरीद के लिए, आप हीटकॉन सेंसर्स के पास सकते हैं, जिनकी टीम आपको सबसे उच्च गुणवत्ता वाले उत्पाद प्रदान करने का वादा करती है।

 

 

 

थर्मोकपल कनेक्टर्स और किसी एक को चुनते समय ध्यान देने योग्य बातें!

थर्मोकपल कनेक्टर ऐसे उपकरण हैं जिनका उपयोग तापमान मापने के लिए उपकरण के दो टुकड़ों को एक साथ जोड़ने के लिए किया जाता है। मूल रूप से, थर्मोकपल कनेक्टर किसी भी औद्योगिक प्रक्रिया में उपकरण का एक महत्वपूर्ण हिस्सा है जिसमें उच्च तापमान शामिल होता है।

  • थर्मोकपल मिश्रथर्मोकपल मिश्र धातु दो अलगअलग धातुओं से बने होते हैं जो एक छोर पर एक साथ जुड़े होते हैं। फिर थर्मोकपल के दूसरे सिरे को सॉकेट में डाला जाता है। थर्मोकपल मिश्र धातुएँ ऐसी धातुएँ हैं जिनका उपयोग थर्मोकपल बनाने के लिए किया जाता है। वांछित गुणों के आधार पर कई अलगअलग मिश्र धातुएं उपयोग की जा सकती हैं। सबसे आम थर्मोकपल मिश्र धातु कॉपरकॉन्स्टेंटन, क्रोमेलएलुमेल, आयरनकॉन्स्टेंटन और प्लैटिनमरोडियम हैं। प्रत्येक मिश्र धातु में अलगअलग गुण होते हैं जो इसे विभिन्न अनुप्रयोगों के लिए उपयुक्त बनाते हैं। उदाहरण के लिए, कॉपरकॉन्स्टेंटन का उपयोग अक्सर उच्च तापमान अनुप्रयोगों में किया जाता है, जबकि क्रोमेलएलुमेल कम तापमान अनुप्रयोगों के लिए बेहतर अनुकूल है।

General Purpose Thermocouples

Mineral Insulated Thermocouples

Molded Transition Thermocouples

 

Thermocouples are crucial temperature-sensing devices used across various industries for their reliability, accuracy, and ruggedness. As the demand for precise temperature measurements grows, the role of thermocouple manufacturers becomes increasingly significant. The manufacturers specialize in crafting thermocouples tailored to meet the diverse needs of industries such as aerospace, manufacturing, automotive, healthcare, and more. Let us delve into the three common types of thermocouples produced by a thermocouple manufacturer: which are (i) General Purpose Thermocouples, (ii) Mineral Insulated Thermocouples, and (iii) Moulded Transition Thermocouples.

Types of Thermocouples

Thermocouples are temperature-sensing devices that consist of 2 different metal wires joined together at one end. When exposed to a temperature gradient, they generate a voltage, known as the thermoelectric voltage, which is proportional to the temperature difference between the two junctions. There are several types of thermocouples, each made from different combinations of metals, and they are categorized based on their temperature range, sensitivity, and application suitability. Some of the most common types of thermocouples are mentioned underneath in detail:

  • General Purpose Thermocouples: These thermocouples are also known as Base-Metal Thermocouples. These are temperature sensors used to measure temperature in a wide range of applications across various industries. They are the most commonly used type due to their simplicity, reliability, versatility & cost-effectiveness. Such thermocouples offer reliable performance in many scenarios, making them a popular choice for a wide range of temperature measurement needs. These consist of 2 different metal wires that are joined together at one end to form a junction. The junction is exposed to the temperature being measured, while the other ends of the wires are connected to a measuring instrument. When there is a temperature difference between the two junctions (the measuring junction and the reference junction), an electromotive force (EMF) is generated. This EMF is directly related to the temperature difference and can be measured by the temperature measuring instrument, which then provides a temperature reading.
  • Mineral Insulated Thermocouples: Mineral-Insulated or MI Thermocouples are designed for more demanding & harsh environments. These thermocouples consist of 2 thermocouple wires placed inside a compacted, high-temperature-resistant mineral insulating material, typically magnesium oxide (MgO). The outer sheath can be made of stainless steel or other high-temperature alloys. Their construction provides exceptional protection against moisture, chemicals, and mechanical damage, making them ideal for applications in industrial processes, aerospace, and laboratories. The compact design allows for faster response times and high accuracy in extreme temperature conditions. Thermocouple manufacturers often customize the MI Thermocouples to meet specific customer requirements, ensuring they can withstand temperatures ranging from -200°C to over 1000°C. Their ruggedness & reliability make them suitable for applications in severe environments like exhaust gas measurements, petrochemical processing, and metal smelting. They are constructed using base metal alloys, such as Type K (Chromel-Alumel), Type J (Iron-Constantan), and Type T (Copper-Constantan). Each type has its own temperature range and characteristics, making them suitable for different applications. 
    • Type K: The Chromel-Alumel combination can withstand temperatures ranging from -200°C to approximately 1260°C. This type of thermocouple is widely used in various industries, including food processing, automotive, and power generation.
    • Type J: The Iron-Constantan combination can operate in a temperature range of -210°C to around 760°C. Its lower temperature limit makes it unsuitable for extremely high-temperature applications.
    • Type T: The Copper-Constantan combination covers a temperature range of -200°C to approximately 370°C. Such type of thermocouple is commonly used in cryogenics, environmental chambers, and HVAC systems.
  • Molded Transition Thermocouples: Molded-Transition Thermocouples are the type of thermocouples specifically designed for surface temperature measurements. They consist of a sensing junction that is embedded in a molded insulating material, such as ceramic or epoxy, to protect the junction and provide electrical insulation. The other end of the thermocouple has a lead wire that connects to the measuring instrument. Their primary advantage is their ease of installation and ability to measure temperature on flat or curved surfaces. They are commonly used for applications in the plastics industry, semiconductor manufacturing, and research labs. Their unique & compact design helps in situations where space is a concern. While these thermocouples provide accurate measurements for surface temperatures, they may not be suitable for extremely high-temperature applications. Thermocouple manufacturers can customize the materials and dimensions of Molded Transition Thermocouples to meet the unique requirements of their customers.

Frequency Needed for Calibration

 

Thermocouple calibration is the process of verifying & adjusting the accuracy of a thermocouple’s temperature measurement. It involves comparing the output of a thermocouple to a reference standard at known temperatures and determining any deviations or errors. Calibration ensures that the thermocouple provides accurate & reliable temperature readings, allowing for precise temperature control and process optimization.

Techniques of Thermocouple Calibration

There are 3 common methods of  calibration:

  • Fixed-Point Thermodynamic Calibration: In this method, the thermocouple is calibrated against fixed points of known temperatures, such as the melting points of pure substances like metals or salts. Examples of fixed points include the freezing point of silver (961.78°C) and the triple point of water (0.01°C). By comparing the output of the thermocouple with the known temperatures at these fixed points, calibration adjustments can be made.
  • The Furnace Method: Also called as the Stirred Bath method, this involves immersing the thermocouple in a temperature-controlled bath or furnace. The bath or furnace is designed to achieve a stable & uniform temperature throughout. The temperature is measured using a calibrated reference thermometer. By comparing the readings of the thermocouple and the reference thermometer at different temperatures, calibration corrections can be determined.
  • Dry Block Calibrator: This happens to be a portable device that consists of a metal block with precision-drilled holes where the thermocouple can be inserted. The block is heated or cooled to specific target temperatures using built-in heaters or coolers. The block temperature is measured using a calibrated reference thermometer. The thermocouple under calibration is inserted into the block, and its output is compared to the reference thermometer readings, allowing for calibration adjustments.

The Need for Thermocouple Calibration

Thermocouples are widely used for temperature measurement in various industries. However, over time, their accuracy may drift due to factors such as aging, exposure to extreme temperatures, mechanical stress, and environmental conditions. Calibration helps identify & correct these deviations, ensuring that the thermocouple continues to provide accurate temperature readings.

Frequency Needed for Thermocouple Calibration

How often calibration is needed largely depends on different factors, such as the type of application for which you need thermocouple, industry standards, as well as regulatory requirements. In general, thermocouples used in critical processes or safety-critical applications should be calibrated more frequently, typically ranging from once a year to once every few months. Less critical applications may require calibration every 1-2 years.

Determining the Last Calibration Date

To know when the last calibration was done, you should maintain proper documentation & records. Calibration certificates provided by accredited calibration laboratories typically include the calibration date, due date, and other relevant information. It is thus important to keep track of these certificates or maintain a calibration log to ensure the thermocouple remains within its calibration schedule.

Quality Certifications

Thermocouples can be certified or calibrated by accredited calibration laboratories that follow international standards, such as ISO/IEC 17025. These laboratories use traceable reference standards and employ qualified personnel to perform the calibration. Calibration certificates provided by these laboratories serve as evidence of the thermocouple’s accuracy & compliance with quality standards.

Troubleshoot Thermocouple Malfunction

A thermocouple is a device used to measure temperature by utilizing the principle of the Seebeck effect. It consists of two different metal wires or alloys, known as thermocouple wires, joined together at one end to form a junction. When there is a temperature difference between the junction and the other end of the thermocouple, it generates a voltage that is proportional to the temperature difference. Thermocouple malfunction is a problem you can face!

Reasons of Thermocouple Malfunction

Here are some common issues:

  • Contamination: If the thermocouple gets contaminated with dirt, soot, or other substances, it can affect its ability to generate an accurate voltage. Contamination can occur due to improper combustion, poor ventilation, or a buildup of debris over time.
  • Damage or wear: Physical damage to the thermocouple, such as frayed wires, bent or broken junction, or corrosion, can disrupt the flow of electrical signals and result in a malfunction. Additionally, regular wear and tear can degrade the performance of the thermocouple over time.
  • Loose connections: Loose or faulty connections between the thermocouple and the gas valve or controller can lead to intermittent or no voltage output. 
  • Faulty pilot light: In gas-powered systems, the pilot light heats the thermocouple to generate the necessary voltage. If the pilot light is not functioning correctly or is not heating the thermocouple adequately, it can result in a malfunctioning thermocouple.
  • Aging or deterioration: Like any other electronic component, thermocouples can deteriorate over time due to aging. This can lead to reduced sensitivity or inaccurate temperature readings.

How to Know if the Thermocouple Is Working?

To determine if a thermocouple is working, you can perform an open circuit test. If the voltage reading is within the expected range and remains stable during the test, it suggests that the thermocouple is functioning properly. However, if the voltage reading is too low or unstable, it may indicate a faulty thermocouple that needs to be replaced.

Steps for Open Circuit Test

  • First, put off the supply of gas.
  • Then, locate the thermocouple.
  • After that, inspect it.
  • Now, disconnect it.
  • After that, measure the voltage.
  • Then, apply heat.
  • You need to monitor the multimeter now.
  • Finally, check for a stable reading.

Know of Thermocouple Malfunction

You can follow these steps:

  • Check for a pilot light: In many cases, thermocouples are used in gas-powered systems, such as furnaces or water heaters, to detect the presence of a pilot light. If the pilot light is not staying lit, it could be a sign of a faulty thermocouple.
  • Test the voltage: Use a multimeter to measure the voltage generated by the thermocouple. Disconnect the thermocouple from the gas valve or controller and place the multimeter probes on the two leads of the thermocouple wires. Heat the junction of the thermocouple with a flame (e.g., a lighter) while monitoring the multimeter. If you don’t observe a change in voltage as the temperature increases, it may indicate a malfunctioning thermocouple.
  • Inspect for physical damage: Visually inspect the thermocouple for any signs of physical damage, such as frayed wires, corrosion, or loose connections. If you notice any damage, it could affect the performance of the thermocouple.

Troubleshoot Thermocouple Malfunction

You can perform the following steps:

  • Inspect the thermocouple & clean if required: Visually inspect the thermocouple for any signs of physical damage, contamination, or loose connections. Clean the thermocouple if necessary.

You Need to Know about the Thermocouple Temperature Measurement Errors!

Most Common Reasons for Thermocouple Temperature Measurement Errors

Heatcon as Your Go-To Purchase Destination

Thermocouples happen to be amongst the most well-known instruments for measuring temperature in the various types of industrial settings owing to their awesome versatility and easy usage. But thermocouple temperature measurement errors can still occur. 

Most Common Reasons for Thermocouple Temperature Measurement Errors

Though these devices are quite reliable, thermocouple temperature measurement errors can always occur because of different causes. Let us discuss some of the most common reasons for such errors along with the solutions to rectify them:

  • Choosing the Inappropriate Thermocouple Type on Transmitter: Different thermocouples like type K, type J, type N, type E, type T, type R, type S, & type B etc., are all designed differently to measure different temperature ranges, accuracies, electric outputs, and have different sensitivities. Using the wrong type of thermocouple can result in inaccurate temperature measurements, which happens to be a common error.
  • Issues with the Thermocouple’s Extension Wires: The extension wire used to connect the thermocouple to the measurement device can introduce errors if it is of poor quality or not compatible with the thermocouple type. Factors such as resistance, insulation, and electromagnetic interference can affect the accuracy of the temperature measurement. If one accidentally reverses thermocouple lead wires’ polarity, then the temperature being measured would become wrong due to the difference in the temperatures of the 2 leads ends. The issue is very much fathomable as red is the usual colour for positive charges, however the red wire inside thermocouple’s cables usually has negative signal. Such coloration is in the thermocouples’ ANSI-standard, however it’s not what many people tend to expect.
  • Innate Differences in the Alloys: Thermocouples rely on the principle of thermoelectric effect, where temperature differences generate voltage. However, there can be variations in the alloys used to construct thermocouples, which can result in inconsistent voltage outputs and measurement errors. Remember, no 2 batches of wires would be totally similar. As alloy percentages tend to vary during each process, errors in thermocouple accuracies tend to be inevitable. 
  • Variations in the Temperatures Around Reference Junction’s Connection: Thermocouples require a reference junction to measure temperature accurately. If the temperature at the reference junction deviates from the assumed value, it can introduce erroneous measurement of temperatures. Factors such as ambient temperature fluctuations and poor thermal contact can affect the reference junction temperature.
  • Thermocouple Grounded at Multiple Locations: Grounding a thermocouple at more than one location can create additional thermoelectric junctions, which can introduce errors in the measurement. These additional junctions can generate unwanted voltages that interfere with the desired temperature measurement. If grounded at multiple locations, a “ground loop” could be formed with the current flowing through the thermocouple from 1 specific ground to another. This may tend to creäte electromagnetic fields that can cause radio-frequency-interference-related issues, which may tend to affect the measurement accuracy.
  • Age of the Thermocouple: Over time, thermocouples can degrade due to factors such as corrosion, oxidation, or contamination. This can lead to changes in the thermocouple’s electrical properties, resulting in measurement errors. Regular calibration and replacement of aging thermocouples are necessary to maintain accuracy. Max temperature exposure, cyclic measurement, & frequency of cycles may tend to impact the metallurgy resulting in such a drift, which is mostly downwards. Sadly, such a drift can’t be forecasted, but 10-20 degrees F errors are quite common.

What Are Thermocouples?

Thermocouples are temperature sensors that consist of two different metal wires joined together at one end. They tend to generate voltages proportional to temperature differences between the junction & wire’s other end. Thermocouples are widely used because they are durable, inexpensive, and can measure a wide range of temperatures. They are commonly employed in various industrial and scientific applications, including temperature monitoring in ovens, furnaces, engines, and electronic devices.

How Do Thermocouples Work? 

Thermocouples are widely used temperature sensors that operate based on the principle of the Seebeck effect. They consist of two dissimilar metal wires joined together at one end, forming a junction. When there is a temperature gradient between the junction and the other end of the wires (known as the reference junction), a voltage is generated across the thermocouple, which is proportional to the temperature difference. Such a phenomenon is called the Seebeck effect. When the junction of the two wires is exposed to a temperature gradient, an electric potential is created across the wires due to the differing electron densities and energy levels of the metals. This potential difference is measured and used to determine the temperature at the junction.

Most Common Temperature Ranges of Different Thermocouple Types

The temperature ranges of thermocouples cover a wide variety of applications, from cryogenic temperatures to extremely high-temperature environments. It is important to select the appropriate thermocouple type that suits the temperature range of your specific application. Here are some most common temperature ranges for different thermocouple types:

  • Type K: -200°C to 1350°C (-328°F to 2462°F)
  • Type J: -210°C to 760°C (-346°F to 1400°F)
  • Type T: -200°C to 370°C (-328°F to 698°F)
  • Type E: -200°C to 900°C (-328°F to 1652°F)
  • Type R: 0°C to 1450°C (32°F to 2642°F)
  • Type S: 0°C to 1450°C (32°F to 2642°F)
  • Type B: 600°C to 1700°C (1112°F to 3092°F)
  • Type C: 0°C to 2320°C (32°F to 4190°F)
  • Type D: 0°C to 2320°C (32°F to 4190°F)

How to Accurately Measure Temperature Using Thermocouples?

To accurately measure temperature, thermocouples require a reference junction, often achieved using an ice bath or a dedicated temperature sensor. Additionally, the voltage generated by a thermocouple is typically small, so amplification or signal conditioning may be necessary to obtain a usable temperature reading.

Accuracies & Temperature Ranges of Different Thermocouple Types?

All thermocouple types have their own temperature ranges & accuracy characteristics. The accuracy of a thermocouple is influenced by factors such as the wire material, manufacturing quality, and the reference junction temperature measurement technique. Generally, the accuracy of base metal thermocouples ranges from ±1 to ±10 degrees Celsius, while noble metal and refractory metal thermocouples offer higher accuracy in the range of ±0.5 to ±1 degree Celsius.

Why Do Various Thermocouple Types Differ in Their Colours?

Thermocouples are color-coded to help users easily identify the type. The colour of the thermocouple wire and the colour of the connector can vary depending on the thermocouple type. The colours provide a quick visual reference for selecting the appropriate thermocouple and ensuring accurate temperature measurements.

Thermocouple Types

There are several thermocouple types, categorized based on the metals used in their construction. The most common types include base metal thermocouples (Type J, Type T, Type E, and Type N), noble metal thermocouples (Type R, Type S, Type C, and Type GB), and refractory metal thermocouples. Each type has specific temperature ranges and characteristics. They are identified by letters assigned to them based on the metals used in their construction.

Differences in Thermocouple Types

Each of the calibrations has a different environment & different temperature range, though the max temperature tends to vary with the wire’s diameter that is being utilised in thermocouples. Though thermocouple’s calibration tends to dictate its temperature range, still the max range is even limited by the wire’s diameter. So, a thin thermocouple might not be able to reach its complete temperature range.

Base Metal Thermocouple Types

  • Type K: Composed of Chromel (Nickel-Chromium) and Alumel (Nickel-Aluminum). Suitable for general-purpose applications and has a wide temperature range (-200°C to 1350°C).
  • Type J: Consists of Iron and Constantan (Copper-Nickel). Often used in low-temperature applications (-210°C to 760°C).
  • Type T: Made of Copper and Constantan. Suitable for cryogenic and low-temperature measurements (-200°C to 370°C).
  • Type E: Comprises Chromel and Constantan. Exhibits good accuracy at moderate temperatures (-200°C to 900°C).
  • Type N: This is made of Nicrosil (74.1 % nickel – 14.4 % chromium – 1.4 % silicon.0.1 % magnesium) & Nisil (95.6 % nickel to 4.4 % silicon). 

Noble Metal Thermocouple Types

  • Type R: Made of Platinum and Platinum-Rhodium (13% Rhodium). Suitable for high-temperature applications (0°C to 1450°C).
  • Type S: Composed of Platinum and Platinum-Rhodium (10% Rhodium). Also used for high-temperature measurements (0°C to 1450°C).
  • Type B: Consists of Platinum-Rhodium alloys (30% Rhodium and 6% Rhodium). Suitable for extremely high-temperature environments (600°C to 1700°C).

Refractory Metal Thermocouple Types

  • Type C: Composed of Tungsten and Tungsten-Rhenium (5% Rhenium). Suitable for ultra-high-temperature measurements (0°C to 2320°C).
  • Type D: Made of Tungsten and Tungsten-Rhenium (3% Rhenium). Used for high-temperature applications (0°C to 2320°C).
  • Type G: These are called WM26Re technically. These have an alloy combination with tungsten (W) & tungsten + 26 % rhenium (W-26 % Re). The maximum operating temperature of this type G is 0 degree Celsius to 2320-degree Celsius. 

Why Is Type K So Much Popular?

Among the various thermocouple types, Type K thermocouples are particularly popular due to their wide temperature range, good accuracy, and relatively low cost. They can be used in a variety of applications, ranging from industrial processes to scientific research. The popularity of Type K thermocouples can be attributed to their versatility, reliability, and availability. The conductor materials that are being utilised this Type K thermocouple tend to be more chemically inert than other types such as Type T & Type J. Though the output of Type K ones tends to be somewhat lower than other Types including Type T, Type J & Type E, still it’s much higher than its nearest competitor (i.e., Type N) & is being in use from pretty long now. 

How to Select the Most Ideal One?

When choosing between different thermocouple types, consider factors such as the temperature range of your application, required accuracy, environmental conditions, and cost. Consult the specifications of the thermocouple types to ensure that you select a thermocouple that meets your specific needs. Additionally, it’s important to consider the compatibility of the thermocouple with the measuring instrument or data acquisition system you intend to use. When choosing between different thermocouple types, there are several factors to consider, as follows: 

  • Temperature Range: One of the primary factors is the temperature range of your application. Different thermocouple types have different temperature limitations, so you need to select a thermocouple that can accurately measure the temperatures you will encounter. If you know the temperature range of your application, you can compare it to the temperature ranges of various thermocouple types. Choose a thermocouple that can comfortably operate within your desired temperature range. Ensure that the chosen thermocouple has a temperature range that covers both the minimum and maximum temperatures you expect to measure. For example, if your application involves measuring temperatures up to 1000°C, a Type K or Type R thermocouple would be suitable since they have temperature ranges that include that range. 
  • Consider Accuracy Requirements: Another important consideration is the required accuracy of temperature measurements. Different thermocouple types have varying accuracy levels, which may be specified by the manufacturer. If you have specific accuracy requirements for your application, ensure that the chosen thermocouple can meet those requirements. Keep in mind that accuracy can also be influenced by factors such as the quality of the thermocouple construction, the calibration process, and the measurement instrumentation used. It’s essential to consider the overall accuracy of the entire measurement system, including the thermocouple and associated equipment.
  • Consider Environmental Conditions: The environmental conditions in which the thermocouple will be used should also be considered. Factors such as corrosive atmospheres, vibrations, and pressure can impact the performance and lifespan of the thermocouple. Some thermocouple types are better suited for specific environments. For example, Type K thermocouples are known for their resistance to oxidation and are often used in industrial applications. On the other hand, Type T thermocouples are suitable for cryogenic applications due to their stability at low temperatures. Consider the specific environmental conditions in which the thermocouple will be exposed and choose a thermocouple type that can withstand those conditions effectively.
  • Consider Cost: The cost of the thermocouple is also an important factor to consider. Thermocouples vary in terms of material composition, manufacturing processes, and availability, which can affect their prices. Evaluate your budget and select a thermocouple that meets your temperature measurement needs while staying within your financial constraints.
  • Conductor Size: Thermocouple wires diameter also required to be considered when long measurements need to be taken. For instance, Type T thermocouples have been rated to 370C/700F, but if the thermocouple has #14AWG wires (with .064” as the diameter) then these are rated for 370C/700F. If the thermocouple that you choose has #30AWG wires, which drops to 150C/300F. 
  • Others: Other crucial considerations tend to be the sheath material (in the immersion probe style), the insulation materials (in case of wires/surface sensors) & sensor geometry.

How to Choose the Right Cartridge Heater?

Some FAQs about Cartridge Heaters

What Are Cartridge Heaters?

Cartridge heaters are tube-shaped types of electric heating elements that could possibly be inserted into drilled holes. These happen to be cylindrical in shape and are commonly used for heating applications. It consist of metal sheaths (usually stainless steel) that encloses a heating coil made of a high-resistance wire, such as nichrome. They tend to give quite localized & very precise heating. These are usually utilized in the heating processes in various industries. The heating coil is wound tightly around a ceramic or magnesium oxide core, which provides electrical insulation and efficient heat transfer. Normally, a cartridge heater tends to be utilised for heating metal blocks from inside. Also, these could be customised to specific watt densities that are based upon the needs of the applications. These heaters are quite often used to heat metal parts by making insertions into drilled holes. For speedy & simple installations, these heaters tend to be made somewhat undersized as compared to their usual diameters.

How Do Cartridge Heaters Work?

These heaters work based on the principle of electrical resistance heating. When an electric current is passed through the heating coil, it generates heat due to the resistance offered by the wire. This heat then gets transported to the containing environment via conduction. Cartridge heaters contain resistive coils wound around by ceramic cores, which are further surrounded by dielectrics that are encased inside metal sheaths. Electrically powered heat transferred through the coils to sheaths tend to cause the sheaths to get heated up. This heat is further transmitted to the metal part that needs to be heated. General purpose drills are generally suitable for drilling holes for installing cartridge heaters in low-to-medium temperature applications (600-degree F or lesser than than). Holes could be drilled 0.003″ to 0.008″ over the supposed size of the drill, yielding 0.009″ to 0.04.” Although this particular fit is a little looser than would allow for optimum transfer of heat, it does help while installing & removing these  heaters, specifically those with longer sheaths. For high power, density is much more significant. Holes must be drilled & countersunk, not simply drilled with a general-purpose bit. All thanks to the tighter fit, the heaters run cooler and have a longer service shelf life.

Operating Temperatures of Cartridge Heaters

The operating temperature of a cartridge heater can vary depending on its design and intended application. However, they are typically capable of reaching temperatures ranging from around 200°C (392°F) up to 1000°C (1832°F) or even higher, depending on the specific design and construction. A cartridge heater could possibly operate at low watt densities, medium watt densities, & even at high watt densities. These have been designed in such a way that they can withstand working temperatures of even up to as large as 1400°F. But the optimum operating temperatures would largely depend upon the kind of application it is being used for. You must also understand that there are several other factors too, which could possibly affect the actual temperatures of industrial heaters & the monitored temperatures of materials during such heating cycles; these factors include watt densities of the cartridge heaters, their tightness inside holes, & thermal conductivity of the said material that is being heated. For applications that involve high temperatures, like the ones above 1000°F, sheathes of incoloy material are usually advisable for max heat transfer & fine durability. It’s even significant if you consider electrical termination of cartridges as per the operating temperatures. When the cartridge heaters are utilised at fairly high temperatures, the electric terminals must be either different than the common lead wires of high temperatures or these cartridges must be designed in such a way that the temperatures surrounding the lead wires are well-maintained at much lower temperatures than the limits of the temperatures of those particular lead wires.

What Is a Cartridge Heater Utilised for?

Cartridge heaters find applications in various industries & processes where localized heating is required. Some common uses include the following:

  • Plastic injection moulding: Cartridge heaters are often used to heat the nozzles or the hot runner systems of injection moulding machines.
  • Packaging and sealing equipment: They are used for heat sealing applications in packaging machines, such as sealing plastic bags or containers.
  • Hot stamping: Cartridge heaters provide the necessary heat for hot stamping machines used in marking or branding processes.
  • Food processing: Cartridge heaters can be used in ovens, cooking equipment, or other food processing applications where localized heating is needed.
  • Heating gases & liquids: Cartridge heaters can be used to heat liquids or gases by immersing them directly into the medium or through indirect heating methods like heat transfer through pipes or vessels.
  • Other uses: Cartridge heaters are often used in hot runner moulds, semiconductors, medical equipment, laminating presses, scientific equipment etc. 

Temperature Sensors & Temperature Controllers for Cartridge Heaters

To control the temperature of cartridge heaters, temperature controllers are utilized. Temperature controllers are devices that monitor & regulate the temperature of the heating element. They typically include a temperature sensor, a control mechanism, and an output to adjust the power supplied to the cartridge heater. Temperature sensors for cartridge heaters are commonly either thermocouples or resistance temperature detectors (RTDs). Thermocouples are made of two different metals joined together, which produce a voltage proportional to the temperature difference. RTDs, on the other hand, use the principle of the change in electrical resistance of a metal with temperature. Both types of sensors provide temperature feedback to the temperature controller. The temperature controller receives input from the temperature sensor and compares it to the desired set temperature. Based on this comparison, the controller adjusts the power supplied to the cartridge heater to achieve and maintain the desired temperature. This is usually done using a feedback control loop that continuously monitors and adjusts the power output.

How to Choose the Right Cartridge Heater?

Choosing the right cartridge heater requires considering several factors to ensure it meets your specific requirements. Here are some key considerations when selecting a cartridge heater:

  • Operating temperature: Determine the maximum temperature required for your application. Cartridge heaters come in various temperature ratings, so select one that can withstand the desired operating temperature without compromising performance or safety.
  • Wattage & voltage: Determine the power requirements of your application, including the wattage and voltage. Ensure the cartridge heater you choose matches these requirements to provide the necessary heating power.
  • Size & shape: Consider the dimensions and shape of the cartridge heater. It should fit properly into the intended heating location or equipment. Consider the length, diameter, and any specific shape requirements to ensure a proper fit.
  • Material & sheath: Choose the appropriate sheath material based on the environment and application conditions. Stainless steel is commonly used for its durability, corrosion resistance, and ability to handle high temperatures. However, other materials like Incoloy or titanium may be suitable for specific applications.
  • Lead wire options: Cartridge heaters typically have lead wires for electrical connection. Determine the length, type (such as fiberglass insulated or silicone insulated), and connection options (such as leads with connectors or bare leads) that best suit your application.
  • Mounting options: Consider how the cartridge heater will be mounted or installed. Different heaters may have specific mounting options such as threaded fittings, flanges, or other custom options. Ensure the mounting method aligns with your requirements.
  • Special features: Depending on your application, you may need additional features such as built-in temperature sensors (thermocouples or RTDs) for precise temperature control or specific insulation options for electrical safety.
  • Application requirements: Consider any additional requirements specific to your application, such as compatibility with certain chemicals, moisture resistance, or resistance to vibrations or shocks.

Some FAQs about Cartridge Heaters

These FAQs provide a general understanding of cartridge heaters and address some common questions. However, specific details and requirements may vary depending on the intended application.

Introducing Resistance-Temperature-Detectors (RTDs)

These happen to be the temperature sensors that tend to consist of a resistor, which alters the resistance value when there are changes in the temperature. These are being used for several years now for measuring temperatures in labs & other industrial processes. These have formed a good reputation for repeatability, accuracy, & stability. Most of the elements of an RTD contain a finely twisted wire that is wound around a glass core or a ceramic. The element is generally very delicate; therefore, it’s usually located in a sheathed protective probe. The RTD element happens to be built of pure materials for withstanding varied temperatures. Material’s resistance changes predictably when there are changes in the temperature; that predicted change is usually utilized for determining the temperatures.

The Origin 

Sir Humphrey Davy saw that metals resistivity showed considerable temperature dependence, and this discovery happened in the same year in which Seebeck discovered thermoelectricity. After 50 years, Sir William Siemens proposed using platinum as the resistance ‘s element.

Advantages of Using RTDs

The resistance temperature detector happens to be the most accurate temperature sensor. In addition to good accuracy, it also offers great stability & excellent repeatability. Such an RTD is even relatively immune to electric noises and are thus suited for temperature measurement in different industrial environments, specifically near generators, motors, & other such high voltage equipment.

RTD Probe’s Construction 

Such probes are the assemblies consisting of one element, one sheath, one lead wire & one terminal/connection. Once the element has been chosen, the wiring & packaging needs are to be decided. Sensors can be connected in many ways & there are unlimited sensors or sensor structures to make the selection.

Wiring Arrangement

For measuring temperatures, the element of the RTD should be joined to a monitoring/control device. Now, as the measurement of the temperature is entirely based upon the resistance of the element, any other resistance that has been added to that circuit (resistance of wires, connections, etc.) can lead to an error in the measurement. Any other wiring than the two-wire configuration allows control/monitoring of the devices to account for unwanted wire resistance & other such resistances inside that circuit. Sensors using a three-wire design happen to be quite common designs utilised for industrial processes as well as monitoring/control applications. The resistance of the wires is considered, provided that all the lead wires are having similar resistance; else errors may occur.

Materials of the Wires

While determining the materials of the lead wire, the correct wires must be selected based on the temperature & environment to which that sensor would be exposed during operation. Temperature is by far the most crucial factor in wire selection, but physical properties like abrasion resistance & water submersion properties could be significant too. The 3 widely popular structures are given as under: 

  • PVC insulated probe provides the temperature range of -40 degrees Celsius to 105 degrees Celsius. It also has nice wear resistance. It is also suitable for water immersion. 
  • PFA insulated RTD probe provides the temperature range of -267 degrees Celsius to 260 degrees Celsius. It also provides supercool wear resistance. It is even perfect for water submersion applications. 
  • Although an RTD probe with fiberglass insulation tends to provide a higher temperature range from -73 to 482 degrees Celsius, its performance is considered less effective when consumed or immersed in water.

The Termination

An RTD probe might be stopped via a connection end, or through a quick disconnect, or by a terminal block or even by an extension wire. There are other finishing styles too. 

The Configuration

As the RTD element, the wire layout & the wire structuring have been chosen, the physical structuring of the sensor must be acknowledged. The configuration of the final sensor largely depends on the type of application needed. Varied sensor configurations are needed for measuring the temperatures of liquids, surfaces, or gas streams.

Widely Popular RTD’s Resistance Materials

  • Platinum (highly accurate & widely popular)
  • Nickel
  • Copper
  • Balco (very rare)
  • Tungsten (quite rare)

RTD standards

There happen to be 2 standards for a platinum RTD. These are 1) the European standard (which is even called IEC standard or the DIN) and 2) the American standard. The European one has been considered the global platinum RTD standard. This particular standard, DIN/IEC 60751 (or only IEC751), needs the RTD for having an electric resistance of 100.00 Ω at 0 degrees Celsius, & also the temperature-coefficient-of-resistance (i.e., the TCR) of 0.00385 Ω/Ω/degree Celsius between 0 degree Celsius & 100 degree Celsius. The amalgamation of temperature coefficient & resistance tolerance tends to determine the resistance & temperature characteristics of such an RTD sensor. The greater is the tolerance of the element, the more the sensor deviates from the general curve & greater will be the variability from 1 sensor to another (which is also called interchangeability). This is significant for those users who require the replacement of sensors & need to curtail any interchangeability errors.

Selecting the Most Ideal RTD 

  • RTD Element: This is RTD’s simplest form. This contains one piece of wire that is wrapped around a glass core or a ceramic. Owing to their small size, such an element is usually utilised where space is quite limited.  
  • RTD Surface Element: This happens to be a special RTD element type. This is made pretty thin, which ensures nice contact for measuring temperatures on a flat surface.  
  • RTD Probe: This happens to be a highly robust RTD form. This contains an RTD element, which has been mounted in a metal tube, which is also called sheath that safeguards the element from the environment.

FAQs

  • Why should one be using an RTD rather than a thermistor sensor or a thermocouple? All types of temperature sensors have specific conditions for which they are ideal. As far as RTDs are concerned, with a wide temperature range up to even 850 degrees Celsius, they could be utilised in most of the industrial processes, even in the high-temperature ones. When an RTD is made with the metals like platinum, these become highly stable, and then they aren’t damaged much by oxidation/corrosion. Other materials including copper, nickel-iron alloy, or just nickel too could be utilised for RTDs. But such materials aren’t used generally as they are having low temperature ability, and they aren’t quite stable also or have repeatable capability as that is there in platinum. So, RTDs provide many benefits, some of which are as follows:
  • Lengthy stability
  • Nice interchangeability
  • Fine accuracy (even better than a thermocouple)
  • Vast temperature range (from around -200 degree Celsius to 850 degrees Celsius)

Liquid’s Temperature Measurement Using an RTD

Sensors that are probe-type are most commonly utilised to measure liquids. These could be quite simple ones having connection heads along with transmitters. Out of these, a widely popular sensor is the quick-disconnect one. It could be utilised as is, with compression fitting for installing flexibly. While doing the measurement of temperature in very harsh environmental conditions like that in plating baths or like in high-pressure systems, these sensors could be covered materials such as PFA Teflon® or contained in a protective housing of thermowell for protecting it against any harsh conditions.

Measuring Air & Gas Temperatures Using RTD Sensors

Measuring air & gas flow is quite a challenge in itself as the rate at which temperature transfers from liquids to sensors tends to be quite slow in the case of liquids. This is why, sensors especially made to be used in air/gas place the sensing element in close proximity to the environment. Such sensors tend to allow the sensing element to be in almost direct contact with the air flow. Such a design is quite popular for measuring temperature of the air in labs, clean rooms, & other such places because the housing design includes elements, which allow air to flow past the element. If such a situation needs some more protection for the sensors, an alternative is to utilise a structure quite like the RTD-860. Such a model has a small-diameter sensor having a mounting flange. The set reacts a little slower to alterations in the air flow, however, it provides better protection for the sensors.

Measuring Surface Temperatures

Measuring surface temperature could possibly be a very intricate thing to do properly & accurately. There’re several styles to make the selection, as per how anyone wishes to mount the sensors, how sensitive the sensor should be to any temperature alterations, and whether or not the installation would be permanent. Some of these are quite speedy & highly accurate responding surface RTDs

RTD Glossary

  • RTD: RTD is the abbreviation for resistance-temperature-detector/device. These indicators work on the principle that the electrical resistance of the conductor alters with the temperature.  
  • RTD Element: Part of an RTD sensor that could be built mostly of nickel, platinum, or copper material. 
  • RTD Probe: This happens to be an assembly consisting of an element, a sheath or housing, a wire & a terminal/connection. 
  • Platinum RTDs: Even called Pt RTDs, these are usually the most linear, most stable, most repeatable and highly accurate of all of the other RTDs. 
  • Thin Film RTD: These consist of a thin layer of base metal, which has been embedded in a ceramic substrate & cut for achieving the wished resistance. 
  • Class A RTD: Highest tolerance & accuracy of RTD elements, Class A (IEC-751), alpha = 0.00385 
  • Class B RTD: The most common of the RTD element tolerance & accuracy, Class B (IEC-751), alpha = 0.00385 
  • Aplha .00385 curve: The European curve corresponds to the tolerance of the “0.1% DIN” standard & conforms to the DIN 3760-standard. 
  • Sheath: The casing, a tube with a closed end, secures the element, and protects it against moisture & the medium to be measured. This also gives protection as well as stability to the transition wires from the sensitive element wires.

Thermocouples

About the Seebeck Effect

How Do Thermocouples Work?

Types of Thermocouples

What’s the Response Time of Thermocouples?

How to Choose the Most Ideal Junction Type?

Choosing the Most Apt Thermocouple

How to select between thermocouples, RTDs, thermistors & infrared devices?

 

What Are Thermocouples? Introducing the Concept of Temperature Measurement

Thermocouples are basically the sensors used to measure temperature. These sensors consist of 2 different metal wires, which have been linked at one of the ends & connected to the thermometer of the thermocouple or other device that is thermocouple-capable at the other end. When it’s properly configured, a thermocouple could possibly assist in providing accurate temperature measurement over a vast temperature range. A thermocouple is known for its versatility as a temperature sensor so generally utilised over numerous applications, from industrial usages to regular utilities & appliances. Owing to its vast range of models & specifications (technical), it’s highly significant to figure out its basic structuring, how it works, the range as to better decide which is the right type of thermocouple & the right type of thermocouple material for your specific application.

 

About the Seebeck Effect

In the year 1821, Thomas Seebeck, who was a German physicist, had discovered the constant current flow inside the thermoelectric circuits when 2 wires of non-similar metals are conjoined at both the ends & one of those ends is heated.

 

How Do Thermocouples Work?

When 2 wires consisting of different metals tend to be connected at both the ends & 1 end is heated, there’s a constant current that flows inside the thermoelectric circuits. If such circuits tend to get broken towards the centre, the Seebeck-voltage, which is the net-open-circuit’s voltage, happens to be a function of the junction’s temperature & the composition of those 2 metals. This tends to imply that when such a junction of 2 metals is either heated or cooled, a voltage tends to be released that could be correlated back to that particular temperature.

 

Types of Thermocouples

Thermocouples tend to be available in varied combinations of metals/calibrations. The most common of them are the “Base-Metal-Thermocouples,” which are called a Type J, Type K, Type T, Type E & Type N. There are even high temperature calibrations, called as “Noble-Metal-Thermocouples,” which are Type R, Type S, Type & Type GB. All of these calibrations tend to have different temperature ranges as well as different environments, though the maximum temperature tends to vary with the wire’s diameter, this is the wire that is utilised inside the thermocouple. Though the thermocouple’s calibration commands the range of the temperature, still the maximum temperature range is even limited by the thermocouple wire’s diameter. This shows that a quite thin thermocouple might not reach the full range of temperature. Type K thermocouples tend to be known for general purposes owing to their low cost & their temperature range.

 

Choosing Thermocouples

  1. First and foremost, try to determine your application where you would utilize the thermocouple.
  2. Then, analyze the ranges of temperatures to which your thermocouple would get exposed to.
  3. Also, consider any of the chemical resistances required for your thermocouple/sheath material.
  4. After that, evaluate your need for abrasion & vibration resistance.
  5. Lastly, list any of the installation needs.

 

Choosing the Type of Thermocouple

As thermocouples measure in vast ranges of temperatures & could be relatively rugged, therefore these have quite frequently industry usages. The criteria given below are used while choosing the right thermocouple:

  • Temperature ranges
  • Thermocouple’s chemical resistance or sheath material
  • Abrasion resistance & vibration resistance
  • Installation needs 

 

What’s the Response Time of Thermocouples?

A time-constant tends to be expressed as that time, which is required by the sensor for reaching 63.2 percent value of a step-change in that temperature under the mentioned conditions. 5-time constants tend to be needed for the sensor for approaching a 100 percent value of the step-change. The exposed-junction-thermocouple tends to provide the speediest response. Additionally, the smaller is the diameter of the probe sheath, the speedier is the response, but the maximum temperature might be lesser. Also, one needs to be aware of the fact that the probe sheath sometimes can’t withstand the full range of temperature of the thermocouple’s type. 

 

How to Choose the Most Ideal Junction Type?

The probes of sheathed thermocouple tend to be available with 1 of the 3 junction types, which are as follows:

  1. Grounded
  2. Ungrounded 
  3. Exposed

Right at grounded one’s tip, the wires of the thermocouple tend to be attached physically towards the inside of the wall of that probe, which leads to proper heat transfer from the outside, via the probe’s wall to the thermocouple’s junction. In the ungrounded one, the junction gets disengaged from the wall, & also the response time tends to be slower than that of the grounded one, but the ungrounded one tends to provide electrical isolation.

Heatcon Sensors happens to be the one-stop-source for all these requirements. With worthy products, effective process measurement and good process control, Heatcon provides you with the best shopping experience for procuring the best-in-class Thermocouples. 

 

Choosing the Most Apt Thermocouple

  • Beaded-Wire Thermocouples: Beaded-wire thermocouples happen to be the simplest thermocouples. They contain 2 pieces of thermocouple wires, which are connected by a welded bead. Now, as these thermocouple beads are exposed, the applications have many limitations. These thermocouples mustn’t be utilised with liquids, which may corrode/oxidize the thermocouple compounds/alloys. Metal surfaces could even be problematic. Metal surfaces, especially pipes, are often utilized for grounding the electrical systems. Indirect connections to the electrical systems can affect measurement of the thermocouples. Generally, such a type of thermocouple happens to be a nice selection for measuring gas temperature. Because it could be very small, it offers quite speedy response times. 
  • Thermocouple Probes: Thermocouple probes consist of a thermocouple-wire that is placed inside the metal tube. The tube wall is called the probe’s sheath. The most common sheath material is stainless steel & Inconel®, which happen to support much higher ranges of temperatures than that of stainless steel, but stainless steel is usually preferred owing to its broader chemical compatibility. Some other more exotic materials for sheaths are available for quite a higher range of temperatures. The thermocouple probe tip is usually available in 3 varying styles, which are grounded, ungrounded & exposed. With the grounded end or tip, the thermocouple remains in contact with the wall of the sheath. The ground one gives faster response time, however it’s quite sensitive to electric ground loops. In the ungrounded junction, thermocouples tend to be separated from the wall of the sheath by an insulating layer. The end or tip of the thermocouples extends outside the wall of the sheath with an exposed junction. These happen to be ideal for measuring air. 
  • Surface Probes: Measuring the temperatures of solid surfaces happens to be tough for many sorts of temperature sensors. For ensuring accurate measurements, the total measuring region of ​​the sensors should be in contact with its surface. This becomes tough while working with rigid sensors & surfaces. As a thermocouple is made of flexible/pliable metals, the junction could be made flat & thin for ensuring maximum contact with rigid solid surfaces. Such a thermocouples is a great selection for measuring the surfaces. Thermocouples could also be turned into rotating mechanisms, so that they become ideal for the measurement of temperature of moving surfaces. 
  • Wireless Thermocouple: Wireless Bluetooth transmitter connects to the smartphones/tables for recording, logging, tracking, measuring & monitoring the temperatures. Such a transmitter measures a variety of sensor inputs to include, but not limit to, temperatures, pH values, RTDs, & relative humidity. Data transfer takes place via wireless Bluetooth technology to smartphone devices or tablets, on which the applications are installed. These applications allow the smartphones to pair & configure multiple transmitters.

FAQs

  • What is the accuracy level & temperature measuring ranges of different types of thermocouples? For knowing about the accuracies & temperature ranges of different types of thermocouples, there is a thermocouple colour coding. It’s significant to recall that both of the accuracy & the carrying capacity depends on some aspects including the alloys of the thermocouples, the measured temperatures, the structuring of the sensors, the sheath materials, the substances that are to be measured, the state of the environment (liquid or solid or gaseous) and the thermocouple-wire’s diameter (if exposed) or the sheath’s diameter (if the wire of the thermocouple isn’t really exposed but sheathed). 
  • Which one should be used; grounded probe or ungrounded one? This largely depends upon the instruments. If it’s possible that there is a reference to the ground (usually seen in controllers commonly with non-isolating inputs), in that case, ungrounded probes would be needed. If the instruments are portable or handheld meters, in those cases, grounded probes would be preferred. 
  • Can multimeters be used to measure temperature using a thermocouple? Thermoelectric voltage overall magnitude largely depends upon the closed (detecting) & open (measuring) ends of the wires of a given thermocouples’ assemblies with alloy leads. Temperature sensors using thermocouples consider the temperature of the measuring side for determining the temperature of the sensing side. Many of the millivolt meters don’t have such a feature, nor they have the non-linear scaling capability for converting the measurement of millivolt into a value of the temperature. Lookup tables can be used to fix a given military voltage reading & calculate the temperature that is being sensed. But the corrected value should be constantly recalculated because it’s usually not constant all the time. Small temperature alterations in the measuring devices & heads would alter this correction value.  

How to select between thermocouples, RTDs, thermistors & infrared devices?

You must acknowledge the capabilities, features & prices of different sensors, along with their existing instruments. Additionally, thermocouples could usually help in measuring temperatures over wide ranges, and also, they are inexpensive & quite durable, but these are not as accurate/stable as Resistance-Temperature-Detectors (RTDs) & thermistors. Resistance-Temperature-Detectors are fairly more stable & they also have a quite wide range of temperature measurement, but these aren’t as durable & inexpensive as the thermocouples are. Now, as they need the utilization of electrical current to measure, RTDs could be prone to errors due to self-heating. Thermistors, on the other hand, are generally more accurate than RTDs/thermocouples but these tend to have a more limited range of temperature measurements. These are also prone to self-heating. An infrared sensor could be utilised for measuring temperatures, which tend to be higher than any other device that too without any direct contacts with the measured surfaces. But these are usually not as accurate and sensitive to the surface-radiation-efficiency (surface-emissivity). Using fibre optic cables, these could help in measuring surfaces, which aren’t in the direct line of sight.
